## Time Twister

Directions: Using the digits 0 to 9, at most one time each, create three different …

1. 90-40=50+0

2. 80-10=60+10

3. You can only use 0 one time.

4. 55-12=43+0

51+32=83-0

21+11=32+0

5. 60-40=10+10

6. 60-10=25+25

7. 9-3=3+3

8. 90-30=30+30

9. Markel Brown Jr

30+30= 50=10

10. Danitza Marenco

It is cause it is 30+30=50+10

11. Daniel Salazar Arias

30-20=1+9

12. karine chapdelaine

87-23=49+15

13. 45-20=16+9

14. Zay'zjon Harris

50-25=17+8

15. Gerald Anderson

17. 60 – 10 = 25 + 25

18. 98-32=54+10
89-14=63+12

19. 78-54=01+23

20. 96 – 32 = 64
50 + 14 =64

21. 35 + 45 = 80 + 10

22. 90-40 = 25+25

23. 9-3 = 5 + 1

24. Gregory Lancaster

60-20=10+30

25. 78-40=23+15
98-32=56+10
89-14=63+12

26. Samantha Bumpass

98 – 74 = 23 + 01

27. 98-10=63+25

28. Hi, I´m a teacher. This website is so cool 🙂

29. 98 – 52=36 +10 (Ivy)

69 – 08 = 24 + 37 (Ali)

97 – 06 = 73 +18 (Mrs Hamer)

80 – 36 = 19 + 25 (Luka)

98 – 16 = 50 + 32 (Aadarsh)

85 – 14 = 69 + 02 (Bayrin)

89 – 13 = 26 + 50 (Ivy)
